    I`ve read a bit abut HDR on this site and was wondering if the software could be used to merge 2 or 3 macro images together to give a greater depth of field. I am thinking of images which are greater than 1:1 where DOF is minimal. Has anyone tried this?

    Try it. There are no rules in this game.

    So far I've tried '3D HDR' - 'IR HDR' and I'm currently working on '3D IR HDR'

    There's a specific filter for that job, Helicon Focus. Seems like a great must have for micro-shooters.

    Some software mentioned here and also the photoshop workbench goes through a tutorial showing how to do this. workbench

    Even though I knew it wouldn't work, I tried the HDR Macro several focus points thing.....and it looked like a bucket of slush.

    You might have success in manually merging the images together - but having tried this myself, it rarely works.

    we do it all the time with pack shots

    Sounds like another PS technique to go in your Book KH.......when you write it.

    Real easy...just need a flat lens like a macro and then focus through the subject and also some with an ever smaller aperture and then erase and blend at will. You can get some very odd DOF effects....almost lens babyish...in fact very lensbabyish

    There is probably a simple algorithm that can be written that would merge a number of macro shots together. I can see how it would work however i think the camera would have to be held in situ at a given angle. That would enable the program to calculate the given depth of field more easily.

    Has anyone seen or heard of such a device and software combo?

    .....yep.


    Image merger in it's simplest form does it.

    Can you see what i mean abou ta device to keep the plane of focus and angle the same though to avoid any unusual effects ??? that way a measure movement can be induced.

    Have you seen a device that does this Keith??? It would sort of be a macro version of a pano head.

    Yes...it's called a tripod which is then fitted with a head - it's real easy and requires no magic or clever gubbins.

    Stick em on a flat bed scanner.....plenty of depth there. Smile

    Keith .. I did think the maths might be a bit beyond you. I'll go and ask a more academic photographer
